TOQZZ whom t may concern.' v

Be it linown that we, Alwin Earann'nn K iizrni'zuo and h/AnsrrALL B. SAncnn'r, citi- 'fxens of the United States, and residents of Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Attachments for '.lype-VVri'tingv Machines; and we do hereby declare the following to be a full, clear, and exact description of the rnvention, such as will enable others skilled 1n the art to which `it appertains to make and use the same.

rlhis invention relates to attachmentsfor typewriting machines and more particularly to rewinding devices for use with stenographic writing machines .-the object of the invention being to provide simple and eicient means which shall be actuated automatically by the operation of the typefor transcribing such matter.

With this and other objects in View, the invention consists -in certain novel features of construction and combinations of parts as hereinafter set forth and' pointed out in the claims.

In the accompanying drawings; Figure 1 is a plan view illustrating the application of our improvements; Fig. 2 is a sideelevation; Fig. 3 is a perspective view of the device; Fig. fl is a transverse sectional view on a reduced scale, and Fig. 5 is a sectional view on the line 5 5 of F ig. 1.

1 represents a stenographic machine and 1a the paper feed devices for the same, suoli as disclosed in application -for patent filled by us on the 7th day of April, 1914, and designated by Serial No. 830,317.

Two arms 2 3 are removably attached to the frame of the machine and project rearwardly therefrom. Between these arms, an oscillatory or rocking foldingframe 4 is disposed,said frame being provided contrally between the ends of one of its sides with a journal 5 mounted in a bearing 6 on the arm 2 and the other side of said frame beingprovided with a bearing 7 which receives a movable spring-pressed journal 8 mounted in the arm 3. A yielding platform Q is mounted within the rocking frame and is normally pressed in an outward u1- ratented Dec. 15,1`9`14L- rection by springs 10 suitably secured Withi in .the frame,-s aid`platform being gulden;- m its movements by means of lu s l1 at itsl corners moving in slots 12 in t e sides of the frame. The rocking frame 4 constitutes a receptacle for the folded paper sheet as the latter is fedvfrom the typewriting machine.

Two vbars 13 are mounted to slide .in suitable guides 14 at each end of the frame 4, and each of these bars is provided at its outer lend with an inverted L-shaped ani) 15. The arms 15 carry folding fingers 16 adapted to project into the frame 4 over the platform` 9 at the several corners thereof. The folding fingers are made with teeth 17 so that they form racks which mesh Iwith segments 18 pivotally mounted on the frameJfj" lnear the ends thereof, sai'd segments formthe hubs of clampsl9 which operate to lingers are being withdrawn from one layer of raper and projected over the next layer, as ereinafter explained. l

At each end of the frame 4, one of the pair of sliding bars 13 is connected with one arm of a small lever 20 pivoted between its ends to the end of the frame, and theV other arm of this lever is connected, by a link 2.1, with the otherbar 13 of the air of I The first-mentioned bar 13 o the pair of bars is provided with a pin or screw 22, W`th which one end of a spring 23 is connected, e other end of said spring bein attached to a pin or screw 2i on the end o the framed. The spring 23 operates to normally pro'ect the folding fingers inwardly over the l in hold the paper strip while the folding.

form and to normally retain the clamps 19 at the outer end of their throw out of the path 25 are pivotally mounted on the ends of the frame #ff-the shorter arm 0f each of said levers normally engaging pin 22 in the frame, while the longer arms of said levers project laterally from lthe frame, and are adapted to be tripped by rollers 27 on the arm 3, when the frame 4 is turned in one, di' rection or the oihez, for the purpose offep erating the folding fingers l6and pape. clamps 19. v A

A yoke 28 is secured to the arm 2 and affords a bearing for one end of a shaft 29, the other end of said shaft bei mounted in a bearing 30 on the arm 2.

wo ratchet wheels 3l-32 are loosely mounted on the shaft 29 and slightly spaced apart. Disks are mounted loosely on this same shaft between the ratchet Wheels, and are provided with arms 34-35 respectively, normally projecting in opposite directions beyond the peripheries of the ratchet wheels.

One end of rod or bar '3G is pivotally connected with the arm 34 and the other end of this rod or bar is connected with a movable part of the mechanism of the typewriting machine, preferably with the paper feed devices as shown in the drawing. A fixed arm 37 projects at right angles from the rod or bar 36, and to the free end of this arm, one

lend of a link 38 is pivoted,the other end of said link being pivotally connected with the arm 35. The rod or bar 36 carries a spring-pressed pawl which engages the f`ineslies with a gear wheel 4l secured to the shaft or journal 5 of the rocking frame 4. A clutch 42 is disposed between the pinion 40 and the ratchet wheel l-one member of said clutch being carried by the pinion and the other member being carried by the ratchet wheel 31. YThe ratchet wheel 32 is 'also provided with a clutch member 42l to coperate with clutch teeth on one end of a sleeve secured to the shaft 29 within the bearing 30. p

rThe fixed arm 2 is made with a rearward extension 44 on which a shifting lever 45 is pivotally mounted, one end of said lever being bifurcated to embrace the pair of ratchet wheels 3l 32 to shift them on the shaft 29 and cause one or the other of said ratchet wheels to be clutched to the shaft. In order to affordextended bearings for the shifting lever against the outer faces of the ratchet wheels, the bifurcated arms of said lever are made with lingers 46 which engage the outer faces of said ratchet wheels. The rearward extension 44 of the arm 2A is provided at its rear end with a tubular portion 47 containing a spring-pressed pin 48 to engage one or another of two notches 49 in the rear end ofthe shift lever to hold the latter in the position to which it may be shifted. The shifting lever 45 is provided with a forward extension 50 which carries a roller 5l to beV engaged by a cam 52 on the rocking frame 4, and a similar roller 58 is carriedby the rear portion of the shifting lever to be engaged by a cam 54 on said rocking frame. i

The free end portion of the paper strip leaving the feed mechanism of the typewriting machine, is placed on the yielding plat ,are

fbrm 9 so as to pass under thei'iieeding fingers at one end of the`latter,`and its -re'e extremity will be held by a spring'clip 55l at the other end of said platform'. During the oscillation of the'paper feed devicesof the typewriting machine, motion Will be 1mparted to one of the ratchet wheels and from the latter through the gears to thev rocking frame toturn the latter. When the frame 4 makes a half turn, the paper Will be folded upon itself, andas said frame approaches the completion of a half turn, the long arm' 26 of one ofthe levers 25 will engage Onenf.

53) on the shift lever,thus causing the latterl to operate to shift the clutch devices on the shaft 29,-disconnecting one of the ratchet wheels from operative rotation to said shaft and connecting the other ratchet wheel-With the latter. from the feed mechanism of the typewriting machine, to turn the frame 4 in thereverse direction. During the first portion of suchv Motion will now be imparted reverse rotation of the frame 4, the varm 26 of lever 25 will leave the roller 27von arm 3, and spring 23 will operate the sliding bars 13 to cause the clamps 19 to be withdrawn and the feeding lingers 16 'to be simulta'-' neously projected over the layer of paper which the clamps vhad been engaging. The' frame will continue to turn until it shall have made a half revolution when the 'same place (the folding fingers and clamps at the other end of the frame 4 being now oper-` ated) and another fold of the paper lwill have been placed in position in the rocking frame. frame and the operations above described will continue during the operation of the typewriting machine, and the paper strip will be foldedback and forth upon itself on the yielding platform and be thus collected or re-wound i'n the rocking or 0scillatory frame. l
